The ETH is one of the best universities of the world (according to several lists and factors). Its name and situation is only comprehensible in combination with the constitution of the swiss state – a university, but not really a university e.g. The stamp of the library reflects this dependence on the swiss state by representing the state (swiss cross, restraint but noticable pathos).

Besides that one defining part of this stamp is the fact that the formal title of the library does not even fit on the stamp itself, so it was necessary to use abbreviations.
